TEKS & Objectives
7.7. Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy.
8.8.C identify how different wavelengths of the electromagnetic spectrum such as visible light and radio waves are used to gain information about components in the universe
7.2.B design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology
We will explore the relationship among force, motion, and energy.
I will investigate the practical effects of energy transfer.
1. Watch video.
Generation Genius Energy Transfer 3-5
NOTE: The DIY demonstration of energy transfer can also be demonstrated by an oven turning electric energy into heat energy.
3. Review vocabulary and complete quiz.
Generator Changes energy from one form to another
Battery Stores energy and changes it from one form to another.
Wind Turbine is a device that produces energy by spinning big blades, which in turns spins a generator to make electricity.
Solar Cell converts energy of sunlight into electrical energy.
3. Transfer energy through collisions.
- Energy can be transferred from one object to another through collisions.
- Place 3 marbles next to each other on a grooved ruler.
- Roll a fourth marble into them. What happened?
- Now try rolling two marbles at the same time into your line of three. What happened?
Speaking of collisions…
What do you call it when 4 giraffes collide?
A giraffic jam
